dumpsterology

The fine art study of dumpster diving. The means of retrieving edible food products that have been discarded. Examples include, cheese paper or on cardboard from hamburger wrap or pizza boxes. Usually high fiber content.
Also, useful household items, may be discovered, newpapers, books, and art objects.

Hey, come over later, Dude, I am giving advanced classes on Dumpsterology at the local Community College at 8 pm.
